Washington, DC 20590 Attention: Docket Operations Subject: Cessna Aircraft Company, Modei680A, Request for Partial Exemption,

14 CFR 25.809(a) Reference: FAA Project Cessna-0721

00 To Whom

It May Concern: Cessna Aircraft Company herby respectfully submits

a request for an exemption

to allow partial relief to 14 CFR 25.809(a), Amendment 116, for the Cessna Model680A Citation Latitude. Regulation

14 CFR 25.809(a), Amendment 116 reads as follows: (a) Each emergency exit, including each flightcrew emergency exit, must be a movable door orhatch in the external walls of the fuselage, allowing an unobstructed opening
to the outside.
In addition, each emergency exit must have meansto pennit viewing of the conditions outside the exit when the exit is closed. The viewing means maybe onor adjacent
to the exit provided no obstructions exist between the exit and the viewing means. Means must also be provided

to pennit viewing of the likely areasof evacuee ground contact. The likely areasof evacuee ground contact must be viewable during all lighting conditions with the landing gear extended
as well as in all conditions
of landing gear collapse Background The Cessna Model 680A
is an executive jet with
a maximum
of 9 passengers and two crew. The overwing exit is a Type III exit. It is located onthe right hand side of the aircraft
in the lavatory. The overwing exit has a window that provides

ameans to pennit viewing of the conditions outside

the exit when the exit is closed. This allows for viewing of the conditions outside the exit when the exit is closed. However, from the location of the overwing exit it is not possible
to view the ground contact. Cessna Aircraft Company One Cessna Boulevard, P.O. Box 7704, Wichita, Kansas 67277-7704, 316/517-6000L390-15-0137 21 January 2015 Page
2 of3 Extent of Relief Request Partial relief
is requested for 14 CFR 25.809(a). Relief
is requested

to the requirement
for ameans to pennit viewing of the likely areasof evacuee ground contact prior to opening the overwing exit. The nature of this petition for pmiial exemption

is similar to the previously granted Exemption 10756 for the Lemjet Model LJ200 and Exemption 10757 for the Embraer Model EMB-550. Public Interest Cessna Aircraft Company competes

in the global market. This aircraft

is aneeded expansion

to the Cessna line of executive jets to compete

in this market. The production
of this aircraft will provide much needed jobs in today's environment. The added interface required
to place the right hand exit in anarea where ground contact could be viewed would require extra weight to interface with the main cabin environment. This would adversely affect the customers with added cost of operation. Affect on Safety In order to provide anexit that would view the ground contact, the exit would need to be moved forward in the cabin. This would mean that the exit would either be located onthe vety leading edge of the wing oroff of the wing. For the best safety of the passengers, the current location of the exit in the lavat01y

is the best location. The current design allows the passengers visibility of the area outside the overwing exit, to assess the immediate danger. Once out of the aircraft, onthe wing, the passenger can view in all directions, assessing the best route to leave the wing. Thus the granting of this exemption would not adversely affect safety of egress. Summmy for Publication

In Federal Register Cessna Aircraft Company requests

a partial exemption from 14 CFR 25.809(a), Amendment 116 for overwing exit onthe Cessna Model 680A. Waiver ofNotice and Public Procedure Cessna respectfully requests, and believes that good cause exists to justify, that action onthis petition not be delayed by publication and comment procedures. Cessna feels this request does not set a precedent, because the relief requested herein
is very similar to exemptions granted previously. Cessna Aircraft Company One Cessna Boulevard, P.O. Box 7704, Wichita, Kansas 67277-7704, 316/517-6000L390-15-0137 21January2015 Page
